按照shape白皮书对于shape格式的介绍，从shape文件中读取空间数据。按照SFF模型对于空间对象的定义，用面向对象的编程语言，实现GIS空间数据结构，并从shape文件中读取的空间数据存储到空间数据结构中。以VC为IDE，调用VC的绘图函数及其他函数，将实习2中的空间数据结构可视化。并实现GIS常用的放大，缩小，漫游等功能。(According to the shape white paper introduction to the shape format, read the spatial data from the shape file. According to the definition of spatial objects in the SFF model, an object-oriented programming language is used to implement the GIS spatial data structure, and the spatial data read from the shape file is stored in the spatial data structure. Using VC as an IDE, VC drawing functions and other functions are called to visualize the spatial data structure in Practice 2. And to achieve GIS commonly used zoom, zoom out, roaming and other functions.)
